In this study, doum fruit pulp (slices) was used to prepare four types of beverages in addition to the traditional doum drink. Distilled water, gum Arabic, CMC and filtration treatments were separately used to prevent precipitate formation (pulp sedimentation). All products were examined for physicochemical, microbial and organoleptic qualities. The traditional doum drink showed a pH value of 5.1, 153 mg/100ml acidity, 7.3 oBrix total soluble solids and 12.83 cps viscosity. It also contained 49.11, 19.33 and 30.64 (mg/100 ml) total sugars, reducing sugars and non-reducing sugars, respectively. Doum drink prepared using distilled water revealed the same pH (5.15), significantly (P≤0.05) lower acidity (134.13 mg/100 ml), TSS (6.0 Brix), viscosity (11.50 cps) and significantly (P≤0.05) higher total reducing and non reducing sugars (66.84, 22.05 and 44.72 mg/100 ml, respectively) compared to the traditional one.When gum Arabic and CMC were separately added, the beverage showed significantly (P≤0.05) lower pH (4.76 and 5.03, respectively), but significantly (P≤0.05) higher acidity, TSS, viscosity as well as considerably higher total, reducing and non-reducing sugars compared to the control. Filtration resulted in a doum beverage with the same pH (5.16), significantly (P≤0.05) lower acidity (93.87 mg/100 ml) TSS (7.0 Brix) viscosity (9.7 cps), but significantly (P≤0.05) higher total, reducing and non reducing sugars (84.20, 47.01 and 36.98, respectively). The fresh traditional doum beverage showed low bacterial total viable count (TVC) of 1.8 x 103 cfu/ml. The TVC was drastically reduced to 3.3 x 102 cfu/ml due to filtration. Manipulation with distilled water, CMC and gum Arabic increased the TVC of the doum drink to 2.9 x 103 – 17.6 x 103 cfu/ml. the five types of doum drinks proved to be free fromSalmonella.The filtered doum drink proved to be organoleptically the best due to its out-standing acceptable sensory properties compared to the other products; in addition it was nearly precipitate free.

Industrial effluents is a threat to the biological species in the aquatic environment. Removal of these heavy metals would make the aquatic world free of pollution and will be a boon. This paper presents the studies carried out on the applicability of microalga namely Spirulina sp. for heavy metal removal from the electroplating industrial effluent. The effects of pH, adsorbent dose, temperature and contact time on the adsorption of chromium by the dry biomass were studied. Concentrations of the metal before and after the experiments were measured by manual method of estimation of chromium. The present study describes the metal absorption by dry biomass of S. platensis that has been used to remove heavy metal pollutants from effluents.

This paper is a result of an innovation project completed by us under Delhi University, Cluster Innovation Centre. In this study, we tried to understand the mechanism of formal and informal sector managing E- waste. The informal sector manages more than 90 percent of India's E-waste. Low infrastructure set-up and operational costs enable them to make the profit and dominate the market. They are not liable to many expenses like rents and legitimate wages, do not invest in modern technology, follow unscientific processes for recycling and extraction, and are not bound by any laws and regulations. Considering the future scenario, it is imperative that the safe management of waste is done in an organised manner with sufficient resources and sustainable recycling technologies on the one hand and effective legislations and monitoring mechanisms on the other. It also calls for the regulatory infrastructure to allow for the protection of workers and community rights. This lack of organisation, which leads to the adoption of inefficient techniques, calls for the development of certain structure in this sector. A need is there to channelize and bring these informal players in the mainstream in order to manage e-waste in a sustainable manner. This study suggests one such process innovation to channelize the electronic waste being produced in different regions of the country. The future scope of this report lies in the regularisation of this sector, to turn it into a lucrative entry point for more organised private players.

Intelligent Control emulates the human intelligence and achieves automation in various areas of Engineering.Intelligent Controls have been used mainly in the areas of Electrical Systems; Machine Intelligence based systems like Robotics. Intelligent Control has been active in various industrial and engineering applications. There is active research in applying Intelligent Controls in distributed computing systems like web based environments. The advent of internet has changed the business models for the service providers and consumers. The Distributed Computing Systems which host various IT and business services are expected to be available with high performance and scalability to meet the desired SLAs. There is absolute necessity in predicting the future trends of the IT environments, recognize the load patterns such that the provisioning of the hardware, software resources is appropriately handled. There are research attempts to explore the applicability of intelligent control in such different areas of computing like infrastructure provisioning and Distributed Systems. In this paper we study the various Intelligent Controls and discuss the recent trends of applying intelligent controls in Distributed Systems such as Web Servers.

Slaishmiki Yonivyapat is considered as one among the 20 Yonivyapat and the symptoms of this condition can be co-related to vulvo vaginal candidiasis which is the commonest infection with an incidence of 75%. Slaishmiki yoni vyapat is characterized by clinical features of Kapha Vriddhi3. The aggravated Kapha along with abnormal functions of Vata reaches the reproductive organs of women results in Kandu (itching in vulva and vagina), Sheeta (discharge without warmth), Picchila (slimy mucoid discharge), mild pain and pallor of the Vulva. For this condition anubhuta yoga of Triphaladi yonivarti was prepared and standardized. The Varti was easy to administer and didn’t revealed any adverse drug reaction too. The drugs posses Vipareeta guna like Rooksha, Teekshna etc. Which combats the Slaishmiki Yonivyapat lakshanas. The study was carried out among 30 subjects where there was highly significant result in relieving the clinical features like Picchilasrava, Sheetasrava, Yoni Kandu, Yoni Vedana and the objective parameter of the pap smear for presence of pseudohyphae of candida albicans too. Triphaladi Yonivarti was administered vaginally to the patient for 7 days twice a day. Follow up vaginal smear was taken on 8th day after treatment to assess presence of candida species. Thus Triphaladi Yonivarti was found highly effective in the management of Slaishmiki Yonivyapat (Vulvo Vaginal Candidiasis).
